These changes store id3 chapter data in ID3v2ExtraMeta and introduce
ff_id3v2_parse_chapters to parse them into the format context if needed.
Encoders using ff_id3v2_read, which previously parsed chapters into the
format context automatically, were adjusted to call
ff_id3v2_parse_chapters.

Several chunked formats (AIFF, IFF,DSF) store ID3 metadata within an 'ID3 '
chunk tag. If such chunks are stored sequentially, it is possible for the
ID3v2 parser to confuse the chunk tag for the ID3 magic number. e.g.
[1st chunk tag ('ID3 ') | chunk size] [ID3 magic number | metadata ...]
[2nd chunk tag ('ID3 ') | chunk size] [ID3 magic number | metadata ...]
Fixes ticket #3530.

This ensures stream[0] is always the audio stream (an assumption made
in dsf_read_packet).
